This is a very basic introduction to
keeping Mediterranean tortoises of the genus Testudo, with special reference to
Testudo graeca, Testudo hermanni and Testudo marginata.

Mediterranean tortoises may well have been
among the most popular European pets of the last 100 years, but for all that,
most keepers know surprisingly little about them. The Tortoise Trust has,
of course, done its best to put this right; even so, we are continually
astonished at some of the questions that crop up repeatedly in our mailbox or
on the ‘phone…. It is worth highlighting some of the more frequent issues here.

Feeding

Mediterranean tortoises in the wild consume
mainly flowers, stalks, and green leaves. They rarely encounter fruit, and
never encounter tinned dog food, ice-cream, bread, pizza, cheese, cakes or some
of the other bizarre “treats” some people seem to think they should be offered.
Most of the tortoises that are fed these inappropriate diets suffer serious,
permanent, damage as a result.Many die.
Don’t do it – and if you are given a tortoise addicted to such foods, break the
addiction immediately. Do not give in, but allow the tortoise to become
sufficiently hungry so that it resumes a normal, healthy diet. This may take
some time – in the interim, offer only safe and healthy foods.

In
captivity, a high fiber,low protein and calcium-rich diet will ensure good
digestive tract function and smooth shell growth.Mediterranean tortoises fed
on cat or dog food, or other high protein food items such as peas or beans,
frequently die from renal failure or from impacted bladder stones of solidified
urates. Peas and beans are also very high in phytic acid, which, like oxalic
acid, inhibits calcium uptake.Avoid reliance upon ‘supermarket’ greens and
fruits which typically contain inadequate fiber levels, excessive pesticide
residues, and are too rich in sugar. Fruit should be given very sparingly or
not at all as it frequently leads to diarrhea, intestinal parasite
proliferation, and colic in these species. Fruit is, however, a routine part of
the diet of many tropical species. See separate caresheets and information relating
to these. They are totally different from Mediterranean species.

Drinking

Unfortunately, some very misleading advice
on this topic has appeared in print in ‘pet care’ books. Tortoises do drink,
both in the wild and in captivity. Drinking is not a sign of ill-health
(although a sudden change in drinking behaviour may indicate that there is a
problem).Ensure that fresh water is
offered daily. Most tortoises prefer to drink by entering a shallow dish or
pool – and can often be stimulated to drink by spraying lightly with a garden
hose in fine weather.

Too much water....

Drowning. Yes, it happens every year. If
you have a pond, make sure that it is completely safe and is 100% ‘tortoise-proof’.
Mediterranean tortoises cannot swim, and any open pool or pond should be
considered as a major hazard.

Theft and security

This is becoming a serious problem. It is
best not to advertise too openly that you have a tortoise in your garden. Prevent
anyone seeing directly into the garden by means of high fences. Lock all gates
securely. Be very careful indeed when allowing strangers access. We have
received several reports of tortoises “disappearing” after window-cleaners or
repairmen have visited recently…

Predators

Foxes, hedgehogs, racoons (USA),
badgers, rats, dogs and even large birds can attack and kill tortoises –
especially juveniles. Ensure that all outdoor accommodation is 100% secure. If
in doubt, bring tortoises in at night.

Behaviour

Male tortoises are typically territorial.
Two males can fight quite viciously, sometimes causing serious injuries. Keep
such males separately. In a restricted enclosure, males can also cause severe
stress and injury to females. Enclosures need to be sufficiently large to
permit escape and hiding from unwanted attentions. On no account, overcrowd
tortoises into an area that is too small. It’s a sure recipe for trouble.
Placing elderly females with younger, active males is also extremely risky. We
advise against this.

Never mix species. We have lost count of
the tales of anguish and woe from people who have “taken a chance” on this –
and who have come badly unstuck. For every case where someone gets away with
it, we estimate that there are 10 others who don’t. Allowing different
tortoises, from other collections, to “meet” your own is also highly
dangerous.We advise strongly against
taking such a risk. There are a number of fatal, non-treatable viral diseases
out there. It only takes one contact, and you could very easily lose every
tortoise you have. Never underestimate this danger. It is very real.

Housing

Small pens on grassy lawns are not
suitable. Fishtanks are not suitable. Tortoises are highly sensitive to their
environments. They make extensive use of “microclimates” and have very specific
needs in terms of temperature, space, and humidity. A well-designed tortoise
habitat (whether indoor or out) can be both attractive and functional. Some
excellent examples are shown on the “Practical Care of Mediterranean (Greek)
Tortoises” video from Carapace Press. It takes effort to provide genuinely
satisfactory accommodation – but your investment will be well repaid by having
happy tortoises, better breeding success and lower veterinary bills.
